Audi Q5 2009: reliability & common MOT faults

In 2025, 66 in every 100 first MOTs on a 2009 Audi Q5 were passes. Most common reason for a fail: Drive shaft joints and boots (front).

Summary

The 2009 Audi Q5 follows the pattern of the model years either side.

What failed most often

  1. Drive shaft joints and boots (front)25 in every 100 failed tests
  2. Suspension arm pins and bushes (front)13 in every 100 failed tests
  3. Coil spring (rear)13 in every 100 failed tests

How we count this. Data: UK MOT open data, 2025. Only Class 4 cars on their first MOT of the year are counted. A car that fails and is fixed at the test station still counts as a fail in the first-attempt rate. These are raw results, not adjusted for age, mileage, or peer mix. The MOT does not test engine or gearbox internals.

Note:

These are patterns across 2009 Audi Q5 vehicles in 2025, not a prediction that any one car will have them. Faults are grouped by part of the car. They come from MOT defect codes, not manufacturer bulletins, recalls or a diagnosis of any one car.

Body and structure

One fault: drive shaft joints and boots (front), 4.1 times as often as on similar cars.

Figures below are measured across the 1,136 failed first attempts in 2025 that had a mileage recorded, which allows a like-for-like comparison.

We only list faults with at least 20 failures and a rate of about 2.0 times that of similar cars, which keeps one-off results out of the list.

Drive shaft joints and boots (front)

Failed on 283 first tests4.1 times as often as similar carsLikely evidence

What it means

A constant velocity boot that is only severely deteriorated is Minor. It is Major once it is missing, split or insecure so that it no longer prevents the ingress of dirt. A transmission joint excessively worn is Major, and graded Dangerous when it is so worn it is likely to fail.

Data: UK MOT open data, 2025. Compared with cars of the same age and mileage.

Noise, emissions and leaks

One fault: diesel engine warning light, 3.5 times as often as on similar cars.

Diesel engine warning light

Failed on 119 first tests3.5 times as often as similar carsLikely evidence

What it means

An engine malfunction indicator lamp that is illuminated to show a malfunction is graded Major on a diesel, but only on the diesels the test covers, which depends on the vehicle type and when it was first used. DVSA lists it under exhaust emissions for compression ignition engines, and the detail line for the row also names an inoperative lamp.

Data: UK MOT open data, 2025. Compared with cars of the same age and mileage.

Suspension

Two faults. The strongest is the coil spring (rear): 3.1 times as often as on similar cars.

Coil spring (rear)

Failed on 144 first tests3.1 times as often as similar carsLikely evidence

What it means

A missing bump stop rubber is not a reason to fail a coil spring. When the vehicle is jacked and lowered, a spring that does not correctly locate as the suspension returns to its normal running position is rejected as insecurely attached. A missing spring is Major, and graded Dangerous where directional control is affected.

Suspension arm pins and bushes (front)

Failed on 146 first tests2.7 times as often as similar carsPossible evidence

What it means

Pins and bushes on suspension arms fail as Major when they are excessively worn. They are graded Dangerous when likely to become detached. DVSA uses the same wording for a suspension joint.

Also noted as an advisory

Testers also noted it as an advisory, worn but not yet failing, on 358 first tests, 3.2 times as often as on similar cars.

Data: UK MOT open data, 2025. Compared with cars of the same age and mileage. Advisories count notes recorded on failed first tests only.

MOT pass rates

How first tests ended, and how the pass rates are counted.

First-attempt pass 66.4% of 3,385 first tests (2025): only cars that passed first time count. Official-style pass 72.3%: cars fixed at the test station also count as a pass. The 6 fixed and the 28 not fixed make the 34 in every 100 that did not pass first time.

What to check at your mileage

How often each fault turned up on a failed first test, by the car's mileage. Read it as: what is likely to need looking at on a car like the one in front of you.

Every figure here is a first-attempt MOT rate from DVSA open data for this model line, for cars of this model year tested in 2025. Each mileage band holds a fifth of the tests. MOTs do not test engine or gearbox internals, so this is a pre-purchase checklist, not a full reliability score.

FAQs

Short answers about how to read this model-year guide.

The 2009 Audi Q5 follows the pattern of the model years either side. Its main cause of failure was Drive shaft joints and boots (front), about 25 in every 100 failed tests. In 2025, 66.4% of 3,385 first MOTs on the 2009 Audi Q5 passed first time (PRS: items fixed at the station the same day, counted as a fail). The official-style rate including PRS is 72.3%. Among 1,136 failed first-attempt MOT tests (test year 2025), Drive shaft joints and boots (front) appears more often than on similar cars (24.9% of those tests; 283 observed failures; about 4.1× more often than similar cars). There is no single reliability score here; this is a pre-purchase checklist built from DVSA open data, not a guarantee for any individual car.
Ranked by how often they were actually recorded, the items that most often failed a 2009 Audi Q5 at the first attempt were Drive shaft joints and boots (front) (24.9%), Suspension arm pins and bushes (front) (12.9%) and Coil spring (rear) (12.7%), each as a share of the year's failed first attempts. That is what goes wrong most often on the car. The common faults table shows a different measure: faults that are unusual compared with similar cars.
Among failed first-attempt tests we highlight patterns that appear more often than on similar cars. Top example: Drive shaft joints and boots (front) (24.9% of those tests; 283 observed failures; about 4.1× more often than similar cars). These are statistical signals, not a diagnosis of any individual car.
Drive shaft joints and boots (front) shows up more often than on similar cars (24.9% of those tests; 283 observed failures; about 4.1× more often than similar cars). That does not prove a design fault. Age, mileage, and how the car was used still matter. Treat it as a pre-purchase checkpoint, not a manufacturer service bulletin.
Common MOT problem areas for the 2009 Audi Q5 include Drive shaft joints and boots (front), Diesel engine warning light, Coil spring (rear). These are the faults that stand out compared with similar cars, not a complete list of what can go wrong on any individual car.
This page highlights MOT failure patterns for the 2009 Audi Q5 (registration year) using UK DVSA open data for the selected test year. Patterns are compared with cars of a similar age and mileage.

No. MOT tests do not cover engine internals, gearboxes, or many electronic modules. Patterns here come from MOT defect statistics only and should not be read as engine or gearbox reliability scores.

About this data

How this page is built and what it can (and can't) say.

These figures come from UK MOT open data for this model year. We surface common failure patterns against similar cars, not a full reliability score, and not a pass/fail verdict on any individual vehicle.

2024 2025

What we include

UK Class 4 cars only. Normal MOT tests (not retests); first test per vehicle per calendar year; results pass, PRS, or fail.

Same-day repairs

PRS means the car failed items that were fixed at the test station and then passed the same day. We count PRS as a first-attempt fail in headline rates so same-day repairs do not hide problems.

How we compare

We compare this model year with other Class 4 cars of similar age and mileage in the same test year. This model family is left out of the peer group so the car is not measured against itself.

What this does not cover

  • MOTs do not cover engine internals, gearboxes, or many electronics; this is not a full reliability score.
  • Common faults come from MOT defect stats, not manufacturer TSBs or recalls.
  • Age and mileage matching reduces, but does not remove, differences in how cars were used and maintained.
  • If the data for a car is too thin to say anything useful, we say so rather than guess.
